Overtaking the speed of light is impossible according to our current understanding of physics. Death on the other hand seems to be due to defects in our bodies (and most living organisms) - nature just hasn't "planned" for them to function for so long and pretty much cut corners. Those defects might be hard to fix with our current technology and/or understanding of medicine, but they're not proven to be impossible. In fact unlike the speed of light, "death" isn't even a single specific event where someone's brain just quits for good but is due to a variety of factors, some of which we can already control and resolve (it used to be that cardiac arrest is guaranteed death, nowadays it's no longer a certainty). In addition, there are many different ways of "solving death". Even if we assume that any living body must die because of some unbreakable law of physics, if we could move someone's consciousness to a new body (or a "virtual machine" in a computer) we've effectively solved the problem anyway.
